This auxil- "iar'y switching device while automatic and affording-some may does not give the signal desirably ahead of. time of actual side steel-in The latter advantage is however secum'cfby the finger lever which may be 'olierated at any time regardless of the tin- 35, that the two deviclels;IL combine to make-afperect signallm' g mec nism. *In 4'is shown that the reversing lever 70 when in position to cause reversing,
